Re: Best thing about 1973 to1987 gm full size trucks

Why is that a good thing?

I could use a little extra space in mine.

I had to make an unplanned stop to pick up my twins from school, which meant my computer briefcase went in the back....in the rain.

I just drove really fast so the water would fly over the top of the cab.

Nobody thought of it until it was too late.

When the squares were designed there was no such thing as an extended cab, and crew cabs were for the railroads and utility companys.

People who drove pickups for personal use drove 1/2 ton regular cab short boxes (...like mine).

When did gm start working on the 1988 redesign ? It had to have been 84 or 85 I would think , I wonder how many square body trucks were riding around on the new chassis for testing .

Not factory.

Ford and Dodge have extended cabs during the comparable year body styles. GM dropped the ball on it.

No sense revising the squarebody product when the release of the GMT400 models was imminent. The front end refresh in '81 was a stopgap measure.

1984 would be a bit late.

My first day in Engineering was the day the truck organization split into carryover product (me) and the new truck (GMT400). That was March 18, 1986, but I'm sure much work had already been started.

I saw one of the body engineers here already this morning. He said Product Planning started in 1982; Engineering was engaged in early 1983 and he joined the group in March of 1984.

None. The integration builds were done from the ground up.

Although.....the introduction of TBI in the 1987 model year was done as "practice" for the '88 GMT400 models (so that we could get a year of production/warranty behind us before the entirely new truck came out).

Oh come on now. That front end went for seven years. Without doing any research I know I've seen Dodge extended cabs as early as '77 and Fords in '78. That gave GM at least ten years to design an extended cab for the square. Even if it took them five that's five more years to sell square extended cabs. I can't see it taking more than three.

I have to say for me I prefer a short bed over a long one and I prefer a 4wd over a 2wd. It is variety that is the spice of life.

Re: Best thing about 1973 to1987 gm full size trucks

I bet GM's sales figures compared to Ford and Dodge during the late 70's were vast enough they didn't see the point of it but kept it in mind for the new body style. Wasn't the 1985? offered with an extended cab on a limited production run?

You are correct that it would probably take about 3 years to pull it off.

I can't comment on when Ford and Dodge came out with extended cabs (and am not curious enough to verify).

But I can say when you are making money hand over fist there's not a lot of motivation to disrupt the flow and deflect a billion dollars of development and investment into a product that is going away.

I don't think anybody ever intended for the square body style to last as long as it did.

You didn't factor in the 5 years of senior management vacillating on whether to do it or not.

Re: Best thing about 1973 to1987 gm full size trucks

Yep, found some info. Okay, so technically GM didn't offer it but Custom Coach offered extended cab 1985 models with most being half ton, a handful of 3/4 tons and at least 1 1-ton made. So not factory but still relative rare. Do a search for 1985 extended cab Chevy and view for yourself.

I know the 3/4 ton crew cab was available in '74. A 1/2 ton short bed variant would have been handy, but I took care of that myself.

"Technically correct" is the best kind of correct.



Custom Coach and Starcraft and their ilk are viewed as "upfitters", not factory.

Ok....much like cars n concepts did the GM t-tops and power sunroof Gbodies back then. Not done on the GM line per se.....but still something you could order through GM then? As in RPO? Interesting nonetheless!

No. No RPO or ability to order through GM.

It's something the upfitter would do after buying the product, with no GM involvement.

In later years we would begin providing "upfitter prep packages", like blunt cut wiring that terminated in locations that were convenient for them, or leaving pieces of interior trim off that were just going to get thrown away, but we didn't do that back in the squarebody era.

Much like my conversion vans. They are GM vans but the only thing factory about the interior are the dashboard and front seat belts. Can't get the roof from the dealer either, and conversion parts were warrantied by the conversion company.

Re: Best thing about 1973 to1987 gm full size trucks

And out of curiosity, I looked it up. Dodge made extended cabs starting in '72, Ford in '74. Seems like ball dropping to me.

If that's the case then I would agree.

I certainly don't remember any back in that time frame but in all fairness it wasn't on my radar.

I wish my 81 C20 was a extended cab long box.
